Accumulating timer

RTO - Accumulating timer

Symbol:

Description:
This timer operates similarly to the On-delay timer. Upon a rung evaluating as TRUE, the timer begins counting in msec. Upon the rung evaluating as FALSE, the timer stops counting, but is not zeroed. The time is retained. On the next rung TRUE condition, the counter continues counting, thereby measuring accumulated TRUE time of the rung. The preset Kn is set to a value in msec. When the accumulated time is greater than the preset value Kn, the done bit is set. Done bit and accumulated time can only be reset by using the RES box.

Range:

T0-T7
